Letters Patent No. 108,546, dated October 18, 1870.

IMPROVEMENT IN SEPARATORS O F THRASHlNG-MACHINES.

The Schedule referred to in these Letters Patent and making part of thesame.

I, AARON WISSLER, of Brnnnerville, in the county of Lancaster and Stateof Pennsylvania, have invented certain Improvements on Separators orThrashing- Machines, of which the following is aspeeifieation.

The first part of my invention consists in hanging the perforated bottomand the chute-bottom so as to swing in opposite directions by the actionof an ordinary double crank and by the intervention of levers or springattachments, thnseach acting as a aprons on the machine, being mainlyimprovements made on the old-fashioned separators, so well establishedin use, and so as to increase their utility.

The drawing exemplifies my arrangement.

Figure 1 is a perspective view of an old-fashioned separator with myimprovements in place.

Figure 2. A side-elevation of the same, to show the relative position ofthe parts.

' On the ordinary frame-work, with its spiked cylinder and coneaves,feeding and conveying trough, with the ordinary perforated bottom andtoothed ridge, B, or rake attachment, I employ also the ordinary shaft1, with a crank bent in the same direction on each side, within the boxor sides S, of the trough or-conveyer supported on the frame-work andbeam A.

The perforated bot-tom C is suspended by the hangers D to the outside,as shown, the sides S being notched out below to allow of the motiongiven to the perforated bottom by the spring-levers 1" on each sideunderneath, which connects with the cranks I, giving the bottom theordinary rise and fall and crank motion.

The chute-bottom B is also suspended by hangers, E, in a reverseposition from the hangers 1),connected with the perforated bottom 0.

' These hangers E are secured to the central fixed, horizontal beam A,so that the motion to the chutebottom B is imparted by a spring-lever,G, secured centrally, and bent upward and attached centrally to thebottom of the perforated swinging bottom 0, thereby actuated by the samecrank motion.

This chute, thus acted upon, delivers the chaff and grain to the screenK, over and under which latter the blast of wind from the fan is drivenin the ordinary manner, only that by means of a link, H, the end of thescreen next the fan is connected with the action of the crank I, or theattachment of the lever l to the crank, so as to give an oscillating orcompound motion to the screen, thereby facilitating the screening;

. H shows a fender or wind-guide, to prevent the blast from going overthe ehute-bott0m, and to concentrate it over and under the vibratingscreen K.

Fig. 1 shows an apron, 0, connected with a hinged cross-piece and strap,1, extending forward to the hand of the feeder, the object of which isto confine the short straw mixed with the chaff and seed when finishingup, and prevent it from passing out or scattering the seed. A hingedupright, N, is shown, with a pin, which holds the strap when the lid orapron O is raised up from the straw bed.

011 the rear end of the perforated bottom 0, I also attach an apron, Q,to prevent any of the short straw or stuff from lodging on thechute-bottom B.

These latter are minor improvements, ,but in combination with action ofthe two swinging bottoms B O, hung in the manner specified, togetherwith the vibrating screen, all actuated by tlicsingle crank-shaft,

produce the most happy results in the operation of.

the separators of this class, and are deemed novel and useful whenarranged, hung, and operated as shown and described.

That I claim as my invention, and desire to secure by Letters Patent,-is-- 1. The arrangement of the two pairs of hangers D -15 and springlevers or connections F G, in combination with vibrating bottoms B G,for the purpose of giving an opposite vertical motion to said bottoms.

2. The arrangement of the links H, attached to screen K and crank-headof lever F, for the purpose of giving an opposite vertical motion toscreen K and bottom 0, as herein described.
